A operating method of electronic apparatus for transmitting rf signal and electronic apparatus

The operation of the electronic device, a method for transmitting an RF signal is disclosed. The method includes the first data point stored in the memory included in the operation, the electronic device to select the output power of the PA included in the electronic device, necessary at the time of transmission of the signal through the antenna contained in the electronic device, comprising: 2 by using at least one of a data point or a first plurality of data points, RF transmission on the basis of the operation and the input power to determine the input power of the PA corresponding to the output power of the PA that is included in the electronic device including the operation of controlling the output power of the circuit, and the plurality of data points is interpolated linearly between the first data point and the second data point it can be generated. It is possible in various embodiments.
